Borealonectes was a marine reptile that swam in the cold Arctic seas 165 million years ago. It had a long neck and four flippers to paddle through the water. It was a fierce hunter with sharp teeth.1 2

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Borealonectes is one of the few plesiosaurs known from the Jurassic of North America.1

It was the first marine reptile from the Canadian Arctic with a well-preserved skull.1 2

The only known fossil includes a skull, neck vertebrae, and the right forelimb.1

Borealonectes lived during the Middle Jurassic, about 165 to 161 million years ago.1 3

It belonged to a group called rhomaleosaurids, which were short-necked plesiosaurs.1 2

The name Borealonectes means 'northern swimmer' in Greek.1

Umfanekiso owenziwe yi-AI: Borealonectes — Umfanekiso owenziwe yi-AI obonisa indlela Borealonectes esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Igama lenzululwazi: Borealonectes
Inikwe igama ngu:: Sato and Wu 20083
Iqela: Iiplesiosauri
Usapho / iclade: Rhomaleosauridae3
Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 165 ukuya ku-162 izigidi zeminyaka (Callovian)3
Izakhiwo zamatye: Hiccles Cove3
Amazwe: iKhanada3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Borealonectes was named in 2008 by Tamaki Sato and Xiao-Chun Wu based on a partial skeleton found in the Hiccles Cove Formation on Melville Island, Canada.1 2
Kusaxoxwa ngayo: Scientists are not sure exactly how big Borealonectes grew, because only one partial skeleton has been found.1
